Maintenance of membrane asymmetry in the resting state cannot be mediated by passive lipid flip-flop alone, since spontaneous translocation of phospholipids across the bilayer has been postulated to be extremely slow (10 â15 s â1), on average a single lipid flip-flop event every 24 h [8] and [9] .ransbilayer lipid motion has been dubbed flip-flop and it is unfortunate that this rather childish term has stayed in the scientific literature, together with the flippase and floppase terms that designate lipid translocating enzymes.
The lipid bilayers that are found in cell membranes have two important characteristics. One of them is that most polar molecules cannot go across the membrane. Polar molecules are attracted to the water inside the cell or to the water outside the cell.However, they cannot interact with the nonpolar tails of the phospholipids within the lipid bilayer. The result is that the interior part of the cell membrane forms a non polar zone that acts as a barrier to polar molecules.hospholipids are molecules that make up the framework of the cell membrane..Phospholipids are lipids in which the long chains or tails are joined to a short polar head that contains phosphorus. The long tails are nonpolar, so water molecules will tend to push them away.
